Unit 4 Global warming 专题练习I.阅读理解AA few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. The scientists were surprised by what they found. They saw that during the next 50 years about 25% of land animals and plants will disappear from the earth. More than 1 million plant and animal species will die out by 2050.The head of the research team, Christ Thomas, who is a professor of conservation biology at Leeds University, said the results of their research were frightening. More than 10% of all plants and animals will disappear from the earth. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we can save many more plants and animals from disappearing.The scientists studied some areas of the world with very rich biology. These areas were Europe, Australia, Central and South America, and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler. In flat areas, such as deserts, plants and animals would have to move very long distances to get cooler, so they are in great danger of dying out. The scientists found many surprising things. For example, they found that half of the 24 species of butterfly they studied in Australia would soon disappear.1.According to this passage, global warming can be best described as ________ to many plants and animals.A.deadlyB.surprisingC.disappointingD.frightening2.What's the purpose of the research led by Christ Thomas?A.To protect animals and plants from global warming.B.To call on people to control greenhouse gases.C.To warn us of the dying out of many animals and plants.D.To study the effect of global warming on animals and plants.3.What can be the best title of this passage?A.Greenhouse effect and global warmingB.Extinct animals in the worldC.A frightening discovery concerning global warmingD.Disappearance of butterflies4.We can learn from the passage that ________.A.about 25% of land animals and plants have disappeared from the earthB.in about four decades more than 1 million plants and animal species will die outC.we can do nothing to save the plants and animalsD.wildlife in flat areas can't find enough foodBHalf of the world's coral reefs have died in the last 30 years. Now scientists are racing to ensure that the rest survive.The planet's health depends on the survival of coral reefs. They are often described as underwater rainforests. In addition, the reefs serve as barriers that protect coastlines from the full force of powerful storms. Corals are used in medical research on treatment for diseases. They are key to local economies, as well, since the reefs attract tourists, the fishing industry, and other businesses, bringing in billions of dollars of revenue (收入).Corals are invertebrates, or animals that lack a backbone. They live mostly in tropical waters. The corals release a substance called calcium carbonate, which forms protective skeletons around them. The skeletons grow and take on vivid colors. This is the result of the corals' symbiotic (共生的), or mutually beneficial, relationship, with algae (藻类) that live in their tissues and give them energy.But corals are particularly sensitive to changes in temperature. A rise of just 1 to 2℃ can force the corals to drive out the algae. Then the corals' skeletons turn white in a process called “bleaching (白化).” Corals can survive in these higher temperatures only for a few months.The problem for the reefs increased greatly during a recent extended El Niño weather phenomenon. In 2015-2016, the longer El Niño warmed the Pacific near the equator, which led to the most widespread bleaching of coral reefs ever recorded. This bleaching event continues to create problems for the world's reefs.In the Indian Ocean, near the islands of the Maldives, about 73% of the coral reefs suffered bleaching between March and May 2016. Areas in the central Pacific were hit the hardest — about 90% of the reefs were destroyed in the waters of the Republic of Kiribati.And the problem is not just global warming. The reefs have also been affected by pollution, coastal development, and overfishing.Scientists remain hopeful that it's not too late to save the reefs, and some are moving ahead on experiments to accomplish that goal. Ruth Gates, director of the Hawaii Institute of Marine Biology, said, “It's high time that we should start thinking outside the box. It's sort of a no-win game if we do nothing.”5.What's the focus of Paragraph 2?A.The vital role of coral reefs.B.The seriousness of pollution.C.The importance of ocean species.D.The difficulties of protecting reefs.6.What is the character of corals?A.They are fish-friendly.B.They are tropical species.C.They depend on algae to survive.D.They can reflect different colors.7.What is the result of the recent El Niño?A.Coral reefs are extinct in Kiribati.B.The Indian Ocean suffered the most.C.Most of the world's reefs fell victim to it.D.It caused record-breaking coral bleaching.8.What do Ruth Gates' words imply?A.Reefs need to be saved urgently.B.Saving reefs is a win-win game.C.It is a challenging job to save reefs.D.Reef-saving efforts have turned out to be fruitless.II.七选五PollutionPollution happens when the environment is dirtied, by waste, chemicals, and other harmful substances (物质). Pollution is a problem all over the world. But it is especially bad in large cities with a lot of industries and cars. __9__ Wildfires, volcanoes, and industrial chemicals cause some air pollution. But most air pollution comes from burning fossil fuels (矿物燃料). These include coal, oil, and natural gas. The burning of fossil fuels may release harmful gases. Air pollution may cause such diseases as cancer and asthma. It also leads to polluted rain that can harm living things. __10__ Finally, air pollution damages the ozone layer (臭氧层), which is important because it protects Earth against harmful rays from the sun.Causes of water pollution are easy to see. People dump (倾倒) garbage and dirty water into rivers, lakes and oceans. Factories or cities sometimes release poisonous chemicals, and other wastes into water. These chemicals may make the groundwater unfit to drink. __11__Littering, or throwing garbage on the ground, is a form of land pollution. Litter can destroy the habitats of plants and animals. The buildup of dangerous chemicals in the ground is another form of land pollution. The chemicals may come from farms or factories. __12__ They may even harm people who eat the polluted plants and animals.Many governments, environmental groups, and ordinary people are working to control pollution. Governments have passed laws to keep people from releasing dangerous chemicals into the environment. __13__ Instead they are getting power from the sun, wind, water, and other energy sources that produce less pollution. Many communities use recycling to reduce pollution.A.Farmers use chemicals to help crops grow.B.This type of pollution may be seen in big cities.C.They also can harm fish and other forms of life.D.These chemicals can spread to plants and animals.E.In addition, air pollution may be a cause of global warming.F.There are three main forms of pollution: air, water, and land.G.Some companies and people are trying to use fewer fossil fuels.III.语法填空The term “eco-friendly” is used to describe activities which are good for the environment. There are different ways in 14 activities can be eco or environmentally friendly, from producing products in an environmentally friendly way to 15 (make) lifestyle changes that are designed to benefit the environment.People take part in eco-friendly activities because they are 16 (concern) about the health of the environment. Environmental problems first 17 (cause) public consciousness (意识) in the late 1900s, when people realized that their activities were having 18 bad effect on the environment. Pollution, overuse of 19 (nature) resources (资源), and other activities 20 (consider) to be hurting the environment, so people began to look into more environmentally friendly ways 21 (live) as well as doing business.It was the belief that investing in green product development would pay off that made many companies make changes. 22 a result, eco-friendly products can be found in many regions of the world today. These products are 23 (usual) made in factories which are environmentally friendly, such as equipment built from recycled materials which are also good for the environment.参考答案I.阅读理解A动植物来说是致命的。

Global warming李仕才一、阅读理解Recently I and other Red Cross volunteers met a group of victims from Hurricane Katrina. We were there, as mental health professionals, to offer ＂psychological first aid＂ and I was struck by the simple healing power of presence. As we walked in the gate to the shelter, we were greeted with a burst of gratitude (感激) from the first person we met. I felt appreciated, but also guilty, because I hadn’t really done anything yet.I first realized the power of presence many years ago when a friend’s mother passed away unexpectedly. I had received a call saying she had just passed away. I wanted to rush down there immediately, but didn’t want to intrude (打扰) on this very personal period of sadness. I was torn about what to do. Another friend with me then said, ＂Just go. Just be there.＂ I did, and I will never regret it.Since then, I have not hesitated to be in the presence of others. Once I sat at the bedside of a young man suffering from the pain of his AIDS — related dying. He was not awake, and obviously unaware of others’ presence. However, the atmosphere was by no means solemn. His family, playing guitars and singing, allowed him to be present with them as though he were still fully alive.In my life, I am repeatedly struck by the healing power of presence. In it, none of us are truly alone. It is not only something we give to others but also changes me for the better.1.Why were the hurricane victims grateful to the author?A. He built shelters for them.B. He gave immediate first aid to them.C. He came to stay with them.D.

AThe number of buses, taxis and other vehicles on Kenya’s roads is growing every day. Now, the country’s first electric-powered motorbikes are coming into the market. The bike is designed to cut down on pollution and aimed at low-income communities. Most motorbikes used in Kenya depend on gasoline as fuel, but not this new motorbike.Three university students developed the new ecotype bike. It catches the sun’s energy, stores it in batteries and uses it to charge the electric motor. Robert Achoge is one of the student inventors. “Our hope is that by th e fifth year, we will be able to cover the whole of Kenya with the electric motorcycle so as to conserve the environment and provide affordable transport.”The students have set up a charging station for the motorbikes in Nairobi. Riders can plug the bikes into any electrical outlet. The small battery can run for 70 kilometres when fully charged. Once the power is used up, the motorbike has to return to the station while another charged battery is connected to the bike. The US African Development Foundation (USADF) is providing finance for two solar-powered charging stations in the Kenyan port of Kisumu.Each ecotype bike costs about $700. One taxi operator says the new motorbike costs less to operate than that running on traditional gasoline. “When it comes to buying gasoline, there’s no need. It’s basically good for various things. As long as you won’t take quite a heavy load(装载量), you can go with it anywhere. Otherwise, it may break down halfway. But now people still have a preference to the gas-powered bi kes.”A Nairobi dealership is selling the ecotype bikes. Businessman Kennedy Kusimba hopes they will become popular. We also know they are more reliable compared to the gas-powered bikes.1.What do we know about the ecotype bike?A.It was developed by the USADF.B.Its energy comes from the sunlight.C.It can charge itself while running.D.It does more harm to the environment.2.What do people think of the ecotype bike?A.It’s better not to use it to carry too much.B.It is a good choice for the long-distance journey.C.It will take the place of gas-powered bikes soon.D.It is much more expensive than a traditional motorbike.3.Where does the text probably come from?A.A research plan.B.An advertisement.C.A government report.D.A science magazine.BSeveral years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Former Mayor Richard Daley later decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual demonstration farm for hydroponics(水培).The farm is on a boat called the Science Barge. Rainwater and purified river water are used to grow lettuces, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems.Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems.Experts say green roofs usually do not get much above twenty-seven degrees Celsius. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.Earlier in 2008, researchers in Texas reported that green roofs can reduce a building’s air conditioning costs by about one fifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers said the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere.4.The author writes Paragraph 1 to .A. tell us what is the green roof designB. tell us Germany is the country that leads or guides the green roof designC. introduce some famous hotels in the worldD. lead to the topic of the passage5.The underlined word “storming” in Paragraph 2 can be replaced by “”.A. attackingB.controllingC.attractingD.managing6.According to the passage, which conclusion is WRONG?A. Sometimes green roofs may break down the house.B. Not all the green roofs can reduce the building’s air conditioning costs equally.C. Different designs of green roofs have different effects on buildings.D. Sedums are a kind of plants native to Texas.CThe Antarctic’s ice-white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar region, invading (入侵) plants and insects, including the flies, cause a major threat.More and more of these invaders, in the form of larvae (幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃over the past three decades. Glaciers have retreated, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before—providing potential green homes for invaders.“The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native life forms.”The Antarctic has several native species of insects. Together with its native mosses, these are now coming under the increased threat from three major sources: visiting scientists, increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of the Antarctic.In 2015, more than 38,000 tourists visited the Antarctic. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic,” said Hodgson.More and more invasive insects and plants have been found on the Antarctic and have required removal. “The insects and plants that are native to the Antarctic have survived there for thousands of years,” said Hodgson. “We have got to act now if we want to save the environment.”7.What does the underlined word “mosses” in Paragraph 2 refer to?A. A kind of plants.B. House flies.C. Coastal areas.D. A kind of animals.8.What is the main cause of the Antarctic going green?A. Scientists’ coming.B. Global warming.C. A growing number of visitors.D. The rapid spread of native planting.9.What do we know about the house flies in the Antarctic?A. They are native to the Antarctic.B. They will disappear due to the cold climate.C. They seriously affected the Antarctic native species.D. They directly fly to the Antarctic from nearby islands.10.What’s the best title for the text?A. The Antarctic is faced with various threatsB. The Antarctic is becoming green and energeticC. More and more scientists get to explore the AntarcticD. Global warming has caused the temperature in the Antarctic to rise up第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

Unit 4 Global warmingⅠ.阅读理解AWildfires and heat waves have been troubling the states of California and Arizona this year. Since 2010, about 6.4 million acres have been burned on average per year. Recent studies have stated that global warming is the cause of these wildfires and higher temperatures, and that the incidence of these natural disasters is likely to increase.As temperatures increase, wildfires become more common. As this cycle progresses, climate change and wildfires both increase frequently and seriously. Forest fires are also developing at higher frequencies as a result of global warming. Firefighters use techniques like back-burning to help prevent further spread of these fires, but these measures are not always effective.Some factors that promote wildfires, such as drought and insect outbreaks, have been linked to global warming as well. Insects that kill trees and other plants make the remains more sensitive to fires, as the plant matter dries out and can more easily be burned. Higher temperatures that result from climate change cause more water to evaporate(蒸发)from reservoirs and lakes, which can lead to drought.With global warming causing higher temperatures, the wildfire seasons of affected areas lengthen. This occurs because summer heat begins to build earlier in the year, and the cooling fall season is delayed. For forests in the southwest United States, the conclusion of snow’s melting indicates the time when fires are able to start. Climate change has caused the melting of snow to occur earlier than it did 50 years ago by about one to four weeks.The global warming trend has hit Southern California extremely hard, and the months of January through April have been hotter this year than they have been for any others in recorded history. This has also caused a drought which has been severe or worse for the entire state. Last year, drought affected only 46 percent of California.With the results from these recent studies, global warming has been linked to an environment that promotes wildfires, by creating higher temperatures and causing drought. California’s wildfire season is just starting, and the damages are likely to be worse as the season continues.1. What does the author intend to tell in the passage?A. Global warming causes high temperatures and wildfires.B. Forest fires have been bringing serious threat to the earth.C. High temperatures make water disappear at a high speed.D. California and Arizona are faced with the extreme weather.2. Why are insects connected with wildfire?A. Because tons of insects exist in the forests.B. Because drought drives insets into the forests.C. Because insects leave the trees dead and dry.D. Because the bodies of insects can burn easily.3. We can conclude from the passage that .A. it is impossible to prevent wildfire from happeningB. the southern states in the USA will see the longest summerC. it is necessary to raise awareness of fire preventionD. California has done nothing to fight wildfiresBFred and Bonnie have 21 children. First they had two of their own and they adopted 19 others from countries around the world. They adopted children from many countries, like Japan, India and Vietnam. Each time they made sure they had music, food, pictures, and books of the child's native country so the children would feel good about themselves.Fred and Bonnie had pre-school children running around the house for 26 years without a break! The washer was always going and clothes hung from one end of the room to the other. Everyone helped out with the housework. The family drank ten litres of milk a day.The couple enjoyed their children. They took care of small problems right away so they wouldn't become big problems. Fred says, "If you have trouble with one of your children, don't worry. Worry doesn't help, and in time your child will be all right."When the children were older, Bonnie began travelling to India. She opened three homes for 170 homeless children. She travels there four times a year to bring food, medicine, and used clothing to the needy children.Back home, Bonnie cooks meals for her seven children still living there. The other children keep in touch. When Tran got married,18 brothers and sisters danced at his wedding.They hope their children will find their own way to help others. They want them to be happy, healthy and independent.Fred says, "Let me light my lamp and never wonder if it will take away the darkness."4. What does the word "adopted" underlined in Paragraph 1 mean ?A. raised children with government support.B. looked after children for parents who were busy.C. provided education for children from poor families.D. brought up someone else's child as his parents.5.

Unit 4《Global Warming》（非谓语动词）例1、The discovery of new evidence led to _________.A. the thief having caughtB. catch the thiefC. the thief being caughtD. the thief to be caught答案为C。
【解析】 lead to这个词组中to是介词，后面跟名词，于是B被排除，the thief是动名词逻辑上的主语，构成动名词的复合结构，与catch之间应是被动关系，故排除A。
常见的带介词to的短语有：(get) be used to, look forward to，look up to, stick to, object to, be devoted to, pay attention to等。
例2、Though _______money, his parents managed to send him to university.A. lackedB. lacking ofC.lacking D. lacked in答案为C。
【解析】 lack是及物动词，后接宾语money。
his parents与lack是逻辑上的主谓关系，要用现在分词作状语。
译文：虽然缺钱，他的父母亲还是设法让他上了大学。
例4、_____ to sunlight for too much time will do harm to one's skin.A. ExposedB. Having exposedC. Being exposedD. After being exposed答案为C。
【解析】在非谓语动词中，用动名词或不定式来作主语，而分词和介词短语不能作主语，因此A、D被排除。
在这个句子中，will do是谓语，缺少主语，要用动名词作主语。
expose 与one's skin是动宾关系，所以要用动名词的被动式being exposed。
译文：在阳光下晒太长时间对人的皮肤有坏处。
例5、____ into use in April 2000, the hotline was meant for residents reporting water and heating supply breakdowns.A. PutB. PuttingC. Having putD. Being put答案：A【解析】put sth. into use “让……投入使用”。
显然，put 和句子主语the hotline 构成被动关系，所以用表示被动的过去分词。
例6、It was unbelievable that the fans waited outside the gym for three hours just ____ a look at the sports stars.A. hadB. havingC. to haveD. have答案：C【解析】动词不定式充当目的状语。
例7、With a lot of difficult problems _______, the newly-elected president is having a hard time.A. settledB. settlingC. tosettle D. being settled答案为C【解析】动词不定式to settle作为difficult problems的定语表示现在或将来要解决的难题；过去分词settle作定语表示已经解决的难题，现在分词的被动式being settled作定语表示正在解决的难题。
例8、More and more people are signing up for Yoga classes nowadays, ____ advantage of the health and relaxation benefits.A. takingB. takenC. having takenD. having been taken答案：A【解析】 take advantage of （利用）和句子主语More and more people 构成主动关系，且和句子谓语sign up for (报名参加)同时发生，所以选择A。
例9、Sandy could do nothing but ________ to his teacher that he was wrong. A. admit B. admitted C. admitting D. to admit答案为A。
【解析】该句中的but是介词，后接动词不定式。
当谓语动词是do，does或did时，后接不带to的不定式；是其他动词时，后接带to的不定式。
该句的谓语是could do nothing，要填动词原形admit。
译文：山德不得不向老师承认自己错了。
例10、He sent me an e-mail, ________ to get further information.A. hopedB. hopingC. to hopeD. hope答案为B。
【解析】现在分词hoping表示与send me an e-mail同时发生的动作。
一些考生认为应该填不定式作目的状语。
不定式作目的状语时，句子的正确形式是：He sent me an e-mail to get further information.不需要hope一词，如果要选择“hoped”时，句子的正确形式是：He sent me an e-mail and hoped to get further information。
“hope”和“sent”作并列谓语。
